+1 to the feature request, though I'm mostly suspending/hibernating my
laptop these days and thus don't suffer too much, except when using
multiple machines.  However, mosh is a huge improvement for many other
reasons (personally I love the way CTRL-C works immediately and the ease
of using mosh over a terrible mobile broadband connection).

When I used ssh more, I did similar and eventually wrote a little script
(attached) to automatically reattach to a named session.  It'd be nice
to update this for mosh.

Cheers,

Mike.
